An object with a density of 1.5 g/mL is placed in a liquid with a density of 1.4 g/mL. Will the object sink or float?

• Sink

• Float

• Suspend

A student observes that ice floats in water. The student can conclude

• The density of ice is less than the density of water

• The density of ice is greater than the density of water

• The density of ice is equal to the density of water

Salt water has a greater density than

• coffee

• soda

• pool water

• plain water

Put the liquids in order from most dense to least dense?

• 4, 3, 2, 1
• 1, 2, 3, 4
• 3, 4, 2, 1, 
• 4, 3, 1, 2

Why do some substances float on water?

• they are warmer than water
• they are cooler than water
• they are more dense than water
• they are less dense than water

Which liquid is the least dense?

• oil
• water
• syrup 
• plastic bottle

Look at this image.  Which object has the LOWEST density in water? How? 

• The Ping Pong Ball because it floats to the top 
• The bolt because it has sunk to the bottom
• The soda cap because it is not just full of air like the Ping Pong ball
